I haven't used any of these units yet in DV, I really suffer in the magic department, and in FFBE you need monks to do a mage's job, because mages are apparently easily distracted from what they were supposed to do.

Mine are a thin square~ish semi-frameless office lady/secretary looking pair, but my prescription is mild (and I take them off to read or do stuff on a computer), so I spend a lot of time not wearing them. I sometimes forget that I've put them back on and reach up to pinch the bridge of my nose or rub my eyes.
